How to File Your Taxes in Canada (2026): A Complete Walkthrough

Filing taxes in Canada sounds intimidating until you do it once. For most people, it’s a 30-minute job using free software that walks you through every question. This is the version of the explanation I wish someone had given my parents when they were figuring it out for the first time.

When are 2026 taxes due in Canada?

For most Canadians, the deadline to file your 2025 tax return is April 30, 2026. If you or your spouse are self-employed, you have until June 15, 2026 to file — but any tax owed is still due April 30. The CRA charges 5% interest plus 1% per month on late balances, so missing the April 30 payment deadline is expensive even if you file later.

What documents do you need to file?

You don’t need to gather paper copies — every slip is auto-loaded into your CRA My Account by mid-March. But it helps to know what to expect:

• T4 — employment income from each job you had in 2025
• T4A — pension, self-employment, scholarship, or other income
• T5 — investment income (interest, dividends from non-registered accounts)
• T3 — trust/mutual-fund distributions
• T2202 — tuition slip if you were a student
• RRSP contribution receipts — for contributions you made in 2025 or in the first 60 days of 2026
• Medical / charitable / childcare receipts — for deductions and credits
• RC62 — Canada Child Benefit slip (informational only)

How to file taxes in Canada (the actual steps)

1. Pick a free NETFILE-certified software. Wealthsimple Tax, TurboTax Free, and StudioTax are all CRA-approved and cost $0 for simple returns. I’ve used Wealthsimple Tax since 2021 and it imports slips automatically once you connect your CRA My Account.
2. Log into CRA My Account. If you don’t have one yet, sign up at canada.ca — it takes about 10 days because they mail you a security code. Once in, your slips will be visible by mid-March.
3. Connect your software to CRA “Auto-fill my return.” This pulls every T4, T5, RRSP slip, and benefit number directly from the CRA. No manual data entry.
4. Add anything Auto-fill missed. Medical receipts, charitable donations, childcare expenses, tuition transferred from a child — these aren’t reported to the CRA, so you enter them yourself.
5. Claim your credits and deductions. The software prompts you for the common ones: basic personal amount, age amount, disability, climate action incentive, Canada workers benefit, etc.
6. Review the summary. Refund or balance owing? Net income? RRSP room? Take 60 seconds to read the summary — it tells you if anything looks off.
7. NETFILE. The software submits directly to CRA over a secure connection. You get a confirmation number on screen — that’s your proof of filing.
8. If you owe, pay before April 30. Use online banking (add “Canada Revenue Agency — Tax-Owing 2025” as a payee) or CRA’s My Payment page. Don’t mail a cheque.

How long until your refund arrives?

Direct deposit through CRA My Account: typically 8 business days after NETFILE. Mail cheque: 8 weeks. Set up direct deposit before you file — that one click can be the difference between getting your money in February vs April.

What if you can’t pay what you owe?

File anyway, on time. The late-filing penalty (5% of the balance + 1% per month) is much worse than the late-payment interest. Once you’ve filed, call CRA at 1-888-863-8657 and set up a payment arrangement. They’ll spread the balance over 6-12 months without freezing your account, as long as you’re communicating.

Should you file even if you owe nothing?

Yes — always. Filing is what triggers your eligibility for the GST/HST credit, Canada Child Benefit, climate action incentive, and provincial benefit top-ups. If you skip a year, you lose those benefits even if you would have qualified. Even teenagers with part-time jobs should file once they turn 19 to start getting the GST credit cheques.
